Door bell rings when key is out and drivers side door is opened on my 2005 chevy impala

If neither switch works it is a bad connection at the motor or bad ground or a bad motor. Remove the door panel unplug the motor push the switch and see if there is 12volts on the wires if there is the motor is bad There are small brushes in the motor that go bad tap on the motor while pushing the switch if it works that way replace it

First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
(NAPA etc will have it.....or the dealer)
Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
Look at the part you have and match it to the part on the heater assembly.
The actuator that is closest to the engine is the drivers side control.
Replace it.
Try your controls and check for heat and cooling on both sides.
The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.

the linkage behind the handle either the retaining clip broke or popped off need to remove the door panel to check and fix

Testimonial: "Thanks I thought it might be a cable or linkage. Much thanks"

SOURCE: good afternoon....what would cause my 2008 Chevy

It could be the power lock motor. You could have a short or bad wiring harness. Might just be a fuse that connects to both. But since you said it's only the driver side. When the power lock motor is bad it can trigger your alarm because they're wired together.

Hope that helps. Good luck.
